iheiiiveiiiieii, prQYisiQi-.l is. mede asiat/3 In the drawings, Figures1 to 4 inclusive show a butter churn comprising a cylindrical bodyportion I having a dished rear end. Projecting from the front of thebody I is a conical portion or mantle 2 which ends in a ehargeanddischarge-opening 3|, which is closed by a cover 3 mounted on hinges liland adapted to be fastened in a closed position by a bolt arrangementIa. 'Surrounding the body portion is a mantle or jacket wall 3 andaround the end are a gable mantle wall 4 and a similar gable mantle orjacket wall 5 arranged at a distance from the former mantle walls inorder to form a heating and cooling mantle space 23, 24. The outer gablemantle wall 5 is provided with a central nipple 8 through which steamand condensate conduits are led to the mantle space 24. These conduitsare arranged in a conductor 2| mounted in the center part I5 of asupport in the form of a cross I4 which is directly attached to abearing-ring 22 which in turn is attached to journals 6. The journalsare horizontally arranged in bearings 32 which are supported bystandards 'I having foot plates 30. The box 2|, to which charge conduitand discharge conduit I6 are connected, can be combined with an axialbearing which may be provided with arrangements to take up the axialpressure. Close to a ring I2, xed to mantle wall 3, a cog ring I3 isarranged to cooperate with a cog wheel I8 placed on a motor shaft 33 ofan electric motor I9. This motor is placed on a special bracket which issupported by the bearing-ring 22 and the system of cross arms I4. To onejournal 6 is connected a helical wheel 26 which is in contact with ahelix 21 which in turn is acted upon by a handwheel 23. By thismechanism the butter churn can be turned in such a way that the opening3| may be directed upwardly or downwardly for charging the ingredientsor for discharging the contents of the container respectively.

The inner side of the bearing-ring 22 is arranged as a bearing surfacefor rolls 34 which are double formed and provided with a central part 35which is of smaller diameter than the rolls. This provides a space for aguide bar 36 between the rolls 34'. The bar is arranged on mantle wall3. A flange 3l on ring I2 prevents the rolls from shifting laterally.

In the drawings, Figures 3 to 7 show sectional views taken through thecontainer body and also modifications in the construction of the dasherblade or wing.

Through the nipple 8 conduits and 2| are provided for the inlet andoutlet of steam, hot or cold air, or water, or other media whichcirculates in the mantle space 23, 24 The container and the surroundingjacket are xed together for rotation. The container can rotate aroundits axis and can, with the jacket, be turned about the axis at bearingpoints 8| in order to tip and empty the contents. The container canrotate upon its axis of rotation in a horizontal or vertical position orat an angle to the horizontal while inclined upwardly or downwardly.

'I'he wing or hollow stirrer I| is arranged in the container and extendsfrom the closed end 4 at a point |2 near the end of the closed end 4 ofthe container to a point |3 which is a good distance into the conicalportion 2. The wing decreases in breadth in such a way that it ends in anarrow tip at point I3. As shown in-Fig. l the stirrer I| is formed bytwo triangular 4 parts Bla and SIb, which are fastened to the containerportions 2 and 4 and project inwardly therefrom radially of thecontainer in spaced relation to each other. However, the stirrer can beformed in any other way. In the stirrer I| a mantle spaceZ 64 is formedwhich communicates with mantle space 23. In Fig. 5 a stirrer Ila isshown which is inclined in relation to the direction of the axis ofrotation. In this ligure, a modified stirrer ||b is shown in dottedlines and is formed of oppositely curved or waving design. This stirrertype can be without the hollow space, is desired. In Fig. 6 a stirrer I|is shown (with starting and end points 63e and 62e) which consists ofone plate and which is used if heating or cooling medium is not desiredto circulate in the wing or stirrer. If desired, the wing can be limitedto the same length of the mantle space.

In Fig. 7 a container la is shown which is made without the conical partso that the body Id is cylindrically continuous and of the same diameterbetween the end wall 4 and the discharge opening 4d. The wing Bld doesnot end in a point but extends therefrom into the center of thecontainer to a point 63011. Fig. 8 shows the churn on supporting columns'la and 1b, one of which supports may form a conductor for the heatingor cooling medium to be supplied to the mantle space.

The wing can have more than one hollow space and can, for example, havea special compartment for electrical heating elements. Also the hollowspace in the wing may be divided into a different number of spaceseither across the wing or lengthwise of the wing. The different spacescan communicate with diierent central charge openings for heating andcooling the medium.

The invention makes it possible to heat the ingredients for ripening aswell as for the interruption of the ripening by cooling and for workingthe butter in the same container. The cooling prevents the butterparticles, etc., from adhering to the wall of the container or to thewing. Cooling and heating can be carried out. during the working itselfwhich is very important in order to get agood churning.

Another advantage of the process according to the invention is that byusing only one wing for working the mass, it can act on the whole massas the unit and can effect a turning of the mass as it is being worked.This is important in the working of the mass. The curved wing furtherincreases the good result of the working.

By the fact that the churn is adjustable to different angles even whenin action, it is possible on the way upward to gather for a workingaction all particles which have collected at the ends of the churn andwhich otherwise would not be properly worked.v

Another important advantage of the process is that the mass isuniformlyworked even though a large quantity of material is worked at the sametime. Since the procedure can be carried out at atmospheric pressure,the arrangement is cheaper in price than other apparatus operating undervacuum.

The apparatus described above as well as the described process can beapplied to other purposes than the production of butter and margarine asfor example, in the production of cheese or to the disinfection orsterilization of certain objects or to cooking operations of allrepeatedly lifting the butter and permitting it kinds. to fall from thelifted position onto an inner What I claim is: y tt wall of saidrotating container.
